My understanding was that the pig cells were not successful in the long term and caused increased dyskinesia - which has been the problem with transplanted neuro cells. I don't think that stem cells are going to be the answer in PD - because of their scatter-shot effect. Too many functions are compromised with too few successes. I think that brain stimulation (refined) will eventually prove to be the best treatment.
